Broken Link Crawl Lite

Broken Link Crawl (Lite)

Extract links from a local HTML file the user supplies, classify them, and flag statically-detectable problems. Completely offline.

Scope and rules

• Reads one saved HTML file — this lite does NOT crawl or fetch URLs, so it cannot detect 404s. It finds structural problems: empty hrefs, javascript: links, dead # anchors, malformed URLs.
• Anchor #id references are verified against ids present in the same file.
• For live link checking (HTTP status, redirects), the full version is needed.

1. Run

Requires Node 18+, zero dependencies.

node <skill-dir>/scripts/links.js page.html

JSON on stdout; exit 1 on broken/flagged links, 2 on usage/read error.

2. Read the report

• links[]: {href, kind: internal|external|anchor|mailto|tel|javascript|other, status: ok|flag, detail}.
• summary: counts by kind and flags.
• unresolvedAnchors[]: #id targets not present in the file.

3. Deliver

List flagged links with the reason. Suggest re-checking live URLs with the full crawler for real 404/redirect coverage.

Lite vs full

The full broken-link-crawl fetches the site, follows links within the domain, checks each URL's HTTP status, and reports real 404s, redirect chains, and timeouts.
